Before implantation 12 (17%) patients underwent cardiopulmonary resuscitation and 32 (46%) patients were ventilated. INTERMACS level 1, 2 and 3 was established in 35 (50%), 29 (41%) and 6 (9%) of patients, respectively. The mean preoperative lactate level was 4.05\u2009mmol\/l. The median support time was 7\u2009days (IR= 4\u201315). In 18 cases, the pump was removed for myocardial recovery, in 22 cases, durable left ventricular assist devices were implanted, and 30 patients died on support. The overall 30-day survival was 51%. Statistical analysis showed that an increase in lactate per mmol\/l [odds ratio (OR) 1.217; P\u2009=\u20090.015] and cardiopulmonary resuscitation before implantation (OR 16.74; P\u2009=\u20090.009) are predictors of 30-day survival. Based on these data, an algorithm for optimal short-term mechanical circulatory support selection is proposed.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>Impella treatment is feasible in severe CS.
